Louisiana State University under the supervision of Dr. Tom Klei. Her research focused on the characterization and regulation of the equine humoral cellular response to Strongylus vulgaris, which further delineated the Th1/Th2 paradigm in horses. Since 2002, Dr. Edmonds has served as Investigator/Parasitologist at Johnson Research, a family-owned independent contract research organization that has been in operation for more than 40 years. She is involved in the development, conduct, and monitoring of target animal safety, pharmacokinetic, and product efficacy studies in beef and dairy cattle and horses. NCVP is excited to have her on board! Dr. Chris Adolph, Veterinary Specialist with Zoetis Dr. Chris Adolph (left) was enormously successful as veterinarian and owner of Southpark Veterinary Hospital in Broken Arrow, Oklahoma for many years. He earned his DVM from Oklahoma State University in 1996 and immediately went into practice where he developed a particular interest in parasitology, which led him to pursue a Master s Degree evaluating the prevalence of helminths and vectorborne disease agents in cats and comparing f e c a l p a r a si t e e g g recovery techniques under the mentorship of NCVP Co- Director Dr. Susan Little, Regents Professor and Krull- Ewing Endowed Chair, at Oklahoma State University. After completing his graduate work in 2013, Chris continued in private practice and as a regular speaker at parasitologyfocused continuing education seminars. Chris decided that he wanted to have a larger voice in the field of parasitology and so after much thought, decided to sell his veterinary practice and take on the role of Parasitology Specialist on the Veterinary Specialty Team at Zoetis where he collaborates with veterinary medical research and development to address the need for novel veterinary Drs. Chris Adolph and Lisette Wigton examine a slide at Southpark Veterinary Hospital. parasite control strategies. Dr. Adolph will continue to speak at continuing education meetings and now serves as the Zoetis representative to the National Center for Veterinary Parasitology. Congratulations on the new position, Chris!

4 P A G E 4 Events NCVP Partners with Journal for Parasitology Series We are happy to announce that the NVCP is partnering with Today s Veterinary Practice to publish a Parasitology series covering topics important to the veterinary health of domestic animals. This series will be written by NCVP residents under the guidance of their faculty mentors. The premiere article of the NCVP resident series, authored by Drs. Yoko Nagamori and Mason Reichard, appears in the May/June 2015 issue of Today s Veterinary Practice and is entitled Feline Tick-Borne Disease. This article contains updated information about ticks and associated tick-borne diseases of cats in the United States. Today s Veterinary Practice can be found online at NCVP Affiliate Resident Dr. Brian Herrin Wins 3MT Competition On March 12, 2015, the same day that NCVP affiliate resident Dr. Brian Herrin (pictured left in the bow tie) took his oral qualifying examinations (and passed!), he competed in the Oklahoma State University Center for Veterinary Health Sciences 3-Minute Thesis Competition...and WON! What a day! Brian s presentation, entitled Lyme Disease: An Expanding Threat, explained the use of mapping in-clinic canine vector -borne disease (VBD) positive test results at the county level in assessing the spread of VBD into new geographic areas. Dr. Herrin is originally from Lindsay, Oklahoma. He earned his Bachelor s in Biochemistry and Molecular Biology in 2009 from Oklahoma State University and then entered the combined DVM- PhD program. He completed his DVM in 2014 and then entered the PhD program full-time, working under Dr. Susan Little at Oklahoma State University to investigate the utility of canine serosurvey data and field tick collection in more accurately determining the distribution of Lyme borreliosis in North America. Although Brian originally considered specializing in pathology, he realized that his passion for parasitology was greater and now plans to pursue ACVM board certification in parasitology.

5 P A G E 5 Events continued... Male and female Ixodes scapularis, commonly known as the black-legged or deer tick. This tick is the vector of Borrelia burgdorferi, the causative agent of Lyme borreliosis, in the northeastern and upper midwestern regions of the United States. Dr. Brian Herrin, affiliate resident with the NCVP, is conducting field and epidemiologic research to better understand the changing distribution of this disease in eastern North America.

Since 2013 the NCVP has been funding research on relevant parasite issues for members of the American Association of Veterinary Parasitologists (AAVP). The first round of funding occurred in 2013/2014. Those projects are coming to fruition and results are beginning to be published! A manuscript entitled, Angiostrongylus cantonensis in introduced gastropods in southern Florida by Dr. Heather Stockdale-Walden of the University of Florida was recently accepted for publication in the Journal of Parasitology. Dr. Stockdale-Walden s research demonstrated that two additional terrestrial snails, Bradybaena similaris and Alcadia striata around Miami, Florida, can serve as intermediate hosts for A. cantonensis. Dr. Rick Gerhold at the University of Tennessee also has a manuscript, Trichomonas gallinae persistence in four water treatments, accepted for publication in the Journal of Wildlife Diseases. Dr. Gerhold s team tested the persistence of T. gallinae in various communal water sources including distilled water, quarry water, bird bath water, and rain barrel water. Their findings indicated that T. gallinae can persist for up to 60 minutes in the various water sources, thus providing a source of infection to naïve birds. Please look for each of these articles in upcoming issues of the respective journals. We are proud to announce that the NCVP will fund a third round of grants in 2015/2016. The upcoming request for proposals will be distributed to AAVP members in May Grants awarded by the NCVP thus far are listed below and on the following page. 2014/2015: Dr. Roberto Cortinas, University of Nebraska-Lincoln Assessment of various essential oils and their constituents for activity versus northern fowl mites.

Continuing Efforts to Promote the NCVP Dr. Susan Little, Co-Director of the National Center for Veterinary Parasitology, continues to spread the NCVP message throughout North America. In the past few months she has shared information about NCVP resources and opportunities for careers in parasitology with faculty, graduate, and veterinary students at Purdue and Virginia Tech, and even through a TEDX presentation here in Stillwater at Oklahoma State. The TEDX talk focused on how parasite control in pets supports the human-animal bond but also addressed how the NCVP supports the discipline of veterinary parasitology. A GIANT Flea...Seriously! Hold on to your hats, everyone creative parasitology outreach concepts just jumped to the next level! Jose Oyola and Debra Nguyen (Oklahoma State, DVM 2017), AAVP student chapter members and parasite enthusiasts, designed and built a giant flea to use as part of the veterinary parasitology exhibit at Oklahoma State University s Center for Veterinary Health Sciences Open House event this spring.
